Hyphen Needed? Posted on 03/20/2013 by n2n Other than a word being forced apart by the right margin, I have no idea when to put a hyphen between words. Thanks to Woe is I by Patricia T. O’Conner, I now know the rules. Use hyphen before the noun: – Gail is the blond-haired gal No hyphen after the noun: – Gail is blond haired. Alway hyphen: – self-, quasi- No hyphen: – Make sense before a noun even when each is used on its own. – Marty is a happy healthy boy.
